Midland Industries 248X12X12 Half Union Adapter Brass

Product Description

The MIDLAND INDUSTRIES 248X12X12 is a brass half union adapter designed to connect SAE 45-degree male flared tubing to a male pipe thread (MPT) port. It serves as a transition fitting in hydraulic and fluid-transfer systems where flared tubing meets a threaded pipe connection. The fitting measures 2.08 inches in length with a 1.06-inch hex and carries a 550 psi pressure rating. Thread dimensions are 1-1/16-14 on the flare end and 3/4-14 on the pipe thread end. This fitting is installed by plumbers, pipefitters, and hydraulic system technicians working on lines that require a secure, leak-resistant union connection.

This adapter is suited for use with aluminum, brass, copper, and steel hydraulic tubing that can be flared to SAE 45-degree specifications. It is commonly installed in residential and light commercial fluid systems, hydraulic lines, and refrigeration or gas distribution applications where a half union configuration is required. The fitting accommodates tubing with a minimum wall thickness of 0.035 inches. Its all-brass construction makes it appropriate for environments where corrosion resistance and reliable sealing are priorities.

Compatibility

Designed for use with aluminum, brass, copper, and steel hydraulic tubing that can be flared to SAE 45-degree specifications. Suitable for flare-to-male pipe thread connections in hydraulic, plumbing, and fluid transfer assemblies.

Installation Notes

Installation is performed by a licensed plumber, pipefitter, or hydraulic technician. Depressurize and drain the system completely before removing or installing any fittings. Use an appropriately sized open-end or box wrench on the hex flat; do not use pipe wrenches on the fitting body. Verify that tubing is flared to SAE 45-degree tolerances and that wall thickness meets the 0.035-inch minimum before making the connection.
